I see a lot of advice online for interviews but it all seems more geared towards corporate and sales interviews, which is fine but there are some things that don't overlap. This is also my first ever in person interview.

My main questions are -

What is a good answer for "what is your greatest weakness?"

And, what questions should I ask at the end of the interview?

Also its entry level, and I have some basic electrical installation experience, but is there any knowledge I should seek out before attending? Thanks for any advice its appreciated.
